BROODER HEATER.

Application filed October 2, 1925. Serial No. 60,090.

This invention relates to improvements in brooder heaters and hasparticular reference to a heater capable of use with illuminating gas orother similar gaseous fuels.

The principal object of this invention'is to produce a brooder heaterwhich will use a minimum amount of fuel and give off a uniform heat.

Another object is to provide means whereby theheat is reflectedlaterally thereby securing the greatest efficiency from the amount offuel employed.

A still further object is to produce a heater of this character which issimple in construction and, therefore, cheap to manufacture.

An additional object is to produce a heater of this character which maybe substituted for the type of brooder heater now used, withoutmaterially altering the construction of the brooder house and otherequipment.

Other objects and advantages will be apparent during the course of thefollowing 1 description.

In the accompanying drawings forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same,

Figure I is a vertical cross section of my improved heater,

Figure II is a front elevation of my heater, showing the movable canopypartly broken away, and Figure III is a top plan view of the reflectorcone.

Many types of brooder heaters are now employed, which use various typesof fuel. These heaters are expensive to operate due to the fact that alarge percentage of the heat rises and passes out of the stack with aconsequent loss. I have, therefore, .devised a heater whereby anexceedingly small flame comparative to the size of the heater suflicesto maintain the required temperature beneath the canopy and by referringto the drawings, it will be noted that the numeral 5 designates a basehaving a plurality of openings 6 therein.

The base 5 has a central opening 7 which communicates with the interiorof an inverted frustrum of a cone 8 open at both ends and forming an airchamber. In the wall of this chamber 8 is formed a door opening at 11.Mounted upon this chamber 8 is an element consisting of an invertedfrustum of a cone also open at both ends and forming a combustionchamber 12 with in which a burner 13 is positioned.

This burner may be of any type capab1e of heating a reflector cone 14:which is provided with a flange 16 which flange rests upon the top ofthe combustion chamber 12. This flange 16 is provided with a pluralityof holes 17 (see Figures I and III).

A dome 18 is superimposed upon the whole structure and secured theretoin any convenient manner. This dome has an outlet 19, through which apipe 21 passes. This pipe extends downwardly to a point in closeproximity to the bottom of the reflector cone 14:. This cone is linedwith a retort cement 22, the purpose of which will be later seen.

This dome 18 is also covered with a coating of cement as shown at 23. Acanopy 2a is slidably supported upon the stack 21 as is bestillustratedin Figure II, and is capable of being raised and lowered toaccommodate for chicks of various ages.

The operation of my heater is as follows When the fuel supply is turnedon and admitted to the burner 13, the same is ignited through the door11. The flame im- 35 pinges upon the reflector cone 14, heating thesame, which heat is reflected against the interior wall of thecombustion chamber 12. Fresh air is drawn through the openings 6 asindicated by the arrows which air passes upwardly through the airchamber 8 coming into contact with the hot surface of the reflector cone1 1, where it is heated to a high temperature. This air then passesthrough the openings 17 as indicated by the arrows, downwardly withinthe cone and upwardly through the stack 21. The result of thisconstruction is that heat is reflected against the sides of the casting12 on ac count of the fact that the cone is lined with retort cement,the stored up heat is considerable, which heat is suflicient to maintainan even temperature beneath the canopy.

This is an important feature, as it often occurs that a sudden change inoutside temperature is injurious to the chicks and itis, therefore,important that the heater maintain as even a temperature as possible,under all conditions, which is not possible with a sheet iron or castiron heater, as the same lose their heat rapidly.

It is to be understood that the forms of my invention herewith shown anddescribed are tobe taken as preferred examples of the same, and thatvarious changes in the shape, size and arrangementof parts may beresorted t without departing from the spirit of the invention or thescope of the subjoined claim.

Having thus described my invention, I claim In a brooder heater, abasehaving a pinrality of openings therein, a circular casting forming anair chamber positioned on said base,-the interior 0 f said air-chambercommunicating with the interior of said base, a sec- 0nd circularcasting forming a combustion chamber positioned on said first mentionedcasting, a reflector positioned in said combustion chamber and having aplastic lining formed therein, means for heating said refiector and saidlining for the purpose of storing and reflecting heat to the wall ofsaid combustion chamber, a dome positioned above said reflector andsecured to said second mentioned casting, said dome having a plasticlining, and a pipe passing through said dome and extending to a point inclose proximity to said reflector.

In testimony whereof I affix my signature.
